Title: Magneto-optical recording medium and magneto-optical recording method
Inventor: KOBAYASHI MASAYA
IPC: G11B11/10
Filed: 1988-03-30
Abstract: PURPOSE:To heighten C/N and to limit low the intensity of a magnetic field impressed from the outside at the time of recording and erasing information by containing specific quantities of Tb, Dy, Fe and Co in a recording layer. CONSTITUTION:A protective layer 3, an intermediate layer 4, a recording layer 5, a protective layer 6 and a protective coat 7 are successively formed on a substrate 2. The contents of the Tb, Dy, Fe and Co in the recording layer 5 shown by atomic % are 20.5<=Tb+Dy<=31.0, 0.088<=Tb/(Tb+Dy)<=0.22, 6.0<=Co<=15.0, and the rest is the Fe substantially.

Title: Production of piping
Inventor: KATAGAI YUICHI
IPC: B23K20/12
Filed: 1987-04-01
Abstract: PURPOSE:To remarkably reduce the man-hour without needing material, tool and edge preparation for welding by pressure-welding a flange, a short pipe with reducer or flange or a reducer with flange to one end of a pipe-like body while rotating the flange, etc., and after that, executing burr-removing in inner face of the pipe and bending works. CONSTITUTION:In the friction pressure welding of the pipe-like body with the flange, etc., the device for using to solid bar-like body can be used. Further, in the burr-removing after pressure-welding, automatic burr-removing device by rotating cutting tool or rotating grinder can be used. The bending work is executed at cold to <=3 inch of the outer diameter and while heating by high frequency to >3 inch. The burr-removing work during friction pressure welding or after pressure-welding and the bending work may be operated without context. However, in the case of preceedingly executing the bending work, as direction of bolt hole does not match with direction of bolt hole for the other body caused by the following pressure-welding work, the body having no bolt hole is used, and after pressure-welding, the bolt hole is bored. But, in case direction of the bolt hole of the other body can easily be displaced, the body having the bolt hole from the first can be used.

Inventor: SUDO KATSUNORI
IPC: F16B23/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a screw provided with a first relief for pressing up the bottom side on the tip of a screwdriver when the screwdriver is reversely rotated on a cross recessed screw, and able to decrease friction torque to be generated in the reverse rotation. SOLUTION: The numerical values described above on the upper parts of figures (a) to (d) indicate the relative rotation angle at the time when a cross-tip screwdriver is turned to the loosening side. The figure (a) shows that the normal screwing attitude. The figure (b) shows that the screwdriver is turned to the loosening side from the state of the figure (a) by only 10 deg. and that a bottom side 112 of the screwdriver starts to be put on a terrace-like first relief 6. The figure (c) shows that the lap allowance to the bottom side 112 of the screwdriver is increased since the first relief 6 is expanded to the center part. The figure (d) shows that the screwdriver 110 is sufficiently pressed up. Since the bottom side of the screwdriver is pressed up by the first relief, friction torque to be generated is decreased.  Since the friction torque is small, there is no possibility that a screw is rotated to the loosening side.

Title: Image sensor
Inventor: ISHIDA TOKUJI
IPC: H04N5/341
Filed: 1988-03-29
Abstract: PURPOSE:To obtain the image signal of a high quality and a little noise by forming a circuit to remove the power source noise of the image signal and a circuit to remove a dark time noise. CONSTITUTION:In a first subtracting circuit 67, the reference voltages of each shift are uniformly made constant and the output signal of a shift resistor in a photoelectric converting part 15 is indicated by a difference from this reference voltage. In a second subtracting circuit 71, a noise base on a dark time electric charge is removed. Thus, the high grade image signal, in which the influence of a power source noise or the influence of the dark time electric charge are removed, can be obtained. Further, since a constitution to execute theses noise removings is wholly provided in one IC chip, it comes to be immune to a noise from an external part. Thus, the image signal of the high quality and a little noise can be obtained.

Title: Operation of nuclear power plant
Inventor: SEKIMIZU KOICHI
IPC: G21C5/00
Filed: 1991-04-10
Abstract: PURPOSE:To operate a nuclear power plant along with compensating excess reactivity without insertion of a control rod into a center part of reactor core during an operational condition very close to a normal output operation by making burnable poison contained in fuel assemblies which are located at a central party of the core, burn more slowly compared to that at a peripheral part of the core. CONSTITUTION:When control rods at the outermost circumferential of reactor core are fully inserted, reactivity goes down by 1.7%. Also, when both recirculation flow rate in allowed to go down from 100% to 85%, void in a coolant reduces by 0.3%. Namely, by reducing the both recirclulation flow amounts reduces down to 85% and inserting control rods at a circumference of the reactor core, 2% excess reactivity can be compensated. At this moment, when the control rods are inserted substantially at the outermost circumference of the core, spatial reactivity should be balanced. This phenomenon can be realized by changing burning characteristic of burnable poison in fuels at a peripheral part and a central part of the core, and consequently by burnning the burnable poison at the peripheral part more quicker and that at the central part more slowly.
